Fantom G Code from nowhere

Software Carbide Create
1

Hi, I’m perplexed.
During a 3D roughing process, the SP5 carried out an unplanned ‘driling procedure’ at the very end of a 4 hour cut. Without warning it plunged a #122 Bull nose bit heavily into a 10mm thick peice of timber. Fortunatley and amaizingly, the bit didn’t break but caused a burning in the workpeace. I know I didn’t have any reason to carry out a drilling process and it certainly wans’t anything I intended.
After a search of the GCode on Motion, I found in line 244,740 to 244,744 the following code.

244,740 - M05
244,741 - (Move to a safe Z to avoid work holddowns)
244,742 - G53G02-5.000
244,743 - (Toll/Mill,0.03,0.00,10.000,45.00)
244,744 - M6T301

I don’t know a great deal about GCode but, it appears that lines 244,741 to 244,743 are the fantom code that has appeard for, what seems to be, no reason.
Can anyone tell me how I can get into the GCoding to change these lines please?
Has this ‘Fantom Coding’ happed to anyone else before?

I don’t think this is your ‘plunge’. It looks more like the beginning of a toolpath.

244,740 - M05 (Spindle Off)
244,741 - (Move to a safe Z to avoid work holddowns)
244,742 - G53G02-5.000 (Z to machine coordinate -5.0. i.e. 5mm below the upper limit)
244,743 - (Toll/Mill,0.03,0.00,10.000,45.00)
244,744 - M6T301 (Tool Change)

I’ve had that happen as well. I wish I would have saved the screenshot of the 3d preview. Mine was also the end of a petty long cut in mahogany.

When I went back and looked at it ( preview) showed 3 definite holes I had not requested or designed.

Deleted toot paths, new tool paths and scrutinized simulation and it was not there CC v778

I’ve decided to re-do the tooling and see if that clears it.

At line 244,740 the machine stops after completing the roughing exercise and then move to hae tool change. Lines 244,743 dosn’t seem right and appears to be the famtom tooling.
It would be nice to be able to edit the GCode directly. Is there a way of doing that?

It appears there are a few ghost commnds in the works.
I have also noticed that accuracy is also in question. I often come accros slithers of materials that the cutting process misses and when I zoom in to design layout I often find the moulding height maps appear off center no matter what I do and it can often leave slithers of material during cutting.
I’m till learning so, onwards and upwards, I’m sure it’s just me.

Can you share the file?
